[libvirt] [PATCH] build: don't include winsock2.h on cygwin

Under cygwin, winsock2.h is intentionally incompatible with, <sys/socket.h>, and checking for existence is wrong. Under mingw, HAVE_WINSOCK2_H is defined on our behalf by gnulib, in a way that does not interfere with cygwin. * configure.ac: Drop unnecessary header check.
